/** * @class Ext.chart.series.CandleStick * @extend Ext.chart.series.Cartesian * @alias series.candlestick * * Creates a candlestick or OHLC Chart. * * CandleStick series are typically used to plot price movements of a security on an exchange over time. * The series can be used with the 'time' axis, but since exchanges often close for weekends, * and the price data has gaps for those days, it's more practical to use this series with * the 'category' axis to avoid rendering those data gaps. The 'category' axis has no notion * of time (and thus gaps) and treats every Date object (value of the 'xField') as a unique * category. However, it also means that it doesn't support the 'dateFormat' prop, * which can be easily remedied with a 'renderer' that formats a Date object for use * as an axis label. For example: * * @example packages=[charts,reactor] * import React, { Component } from 'react'; * import { Container } from '@extjs/ext-react'; * import { Cartesian } from '@extjs/ext-react-charts'; * * export default class MyExample extends Component { * * store = Ext.create('Ext.data.Store', { * fields: ['time', 'open', 'high', 'low', 'close'], * data: [ * { 'time': new Date('Jan 1 2010').getTime(), 'open': 600, 'high': 614, 'low': 578, 'close': 590 }, * { 'time': new Date('Jan 2 2010').getTime(), 'open': 590, 'high': 609, 'low': 580, 'close': 580 }, * { 'time': new Date('Jan 3 2010').getTime(), 'open': 580, 'high': 602, 'low': 578, 'close': 602 }, * { 'time': new Date('Jan 4 2010').getTime(), 'open': 602, 'high': 614, 'low': 586, 'close': 586 } * ] * }) * * render() { * return ( * <Cartesian * store={this.store} * series={[{ * type: 'candlestick', * xField: 'time', * openField: 'open', * highField: 'high', * lowField: 'low', * closeField: 'close', * style: { * ohlcType: 'ohlc', * dropStyle: { * fill: 'rgb(255, 128, 128)', * stroke: 'rgb(255, 128, 128)', * lineWidth: 3 * }, * raiseStyle: { * fill: 'rgb(48, 189, 167)', * stroke: 'rgb(48, 189, 167)', * lineWidth: 3 * } * } * }]} * axes={[{ * type: 'numeric', * position: 'left', * fields: ['open', 'high', 'low', 'close'], * title: { * text: 'Sample Values', * fontSize: 15 * }, * grid: true, * minimum: 560, * maximum: 640 * }, { * type: 'time', * position: 'bottom', * fields: ['time'], * fromDate: new Date('Dec 31 2009'), * toDate: new Date('Jan 5 2010'), * title: { * text: 'Sample Values', * fontSize: 15 * }, * style: { * axisLine: false * } * }]} * /> * ) * } * } */ /** * @cfg {String} openField * The store record field name that represents the opening value of the given period. * @accessor */ /** * @cfg {String} highField * The store record field name that represents the highest value of the time interval represented. * @accessor */ /** * @cfg {String} lowField * The store record field name that represents the lowest value of the time interval represented. * @accessor */ /** * @cfg {String} closeField * The store record field name that represents the closing value of the given period. * @accessor */
